Application led April 22, 1909. i Serial No. 491,478.

To `all whom may' concern:

Be it knownv that I, Libri) B. HORNBECK,

` of Minneapolis, Hennepin county, Minnesota,

have invented certain new and-useful linprovements in Lamp-Hangers. ofwhich the following is a specification.

The object ofmy invention is to provide a Support or hanger for' anincandescent light, which will take up the jar or shock incidentalv tothe moving of furniture around a house, Athe passing of street carsy orany jar that would produce vibration ot" the lamp suilicientito causebreakage of the filament. l

A further obj-eetof the invention is to provide a lamp hanger havinmeans to pre vent the `transmission of vi )ration to the lamp andhence'adapt-y it for use on railway cars.

The inventlon consists generally in various constructions andcombinations, all as hereinafter describedand partlcularly pointed -outin the claims.

In the accompanying drawings, forming part of this specification, Figure1 is a ver-' tical, sectional view of anineandescent lamp holder,embodying my invention, Fig. 2 is a sectional view' illustrating theconstruction shown in Fig. 1 taken on a section line at an, angle to thesection line of Fig. 1.

Fig. 3 is a sectional View on the line X-X of Fig. 1, Fig.` 4 is asectional view on the "Inihe drawing, 2 represents a d omc or casing and3 a ppe or hangerin which the Wires' 4 are con ucted to the lamp. Thedome 2 has an opening 5 in its to in which a shell 6 is fitted andsupported y a sleeve.

7 onthe lower end of the pipe 3. The dome closes the top of theshell andforms there'k with a Casin inelosing the lamp socket and supporting t eglobe. The dome 2 is adapted to slide on the shell 6 tol allow the lampto adjust itself at an angle tothe vertical,

for the convenience" of the user, or to permit swaying of the lamp whenit is used on moving car. Below the dome 2 is a cylindrical shell'8having its upper end teleseop ingwith the lower portion of the dome 2and provided at its lower end with a spring device 9, which engages andsupports a shade or globe 10. Within the dome 2, a' block 11 ofinsulating material is arranged. A bushingbfinsulatin material isprovided within the sleeve 7 -an a bar 12, also of insulating v materialhas its ends supported in the sleeve Specification of Letters Patent,

Patented May 3G), 1911.

7 'anu carries an insulating yoke' 13, which is attached at its ends toeye bolts 14,.'secured to the block 11. ,l prefer to' provide thisinsulating bar and yoke to'prevent short circuiting, in case theinsulationisworn oit the wires #1. The bushing also prevents the wiresfrom contacting with the metallic sleeve. The wires 4 are attached tobolts 15, which 'pass through the block l1l and conductors 16 lead fromthe bolts 15 to a lamp socket 17. This socket is carried by a.4 block18. also otuinsulating material, and comparatively light coil springs 19are interposed hetween the blocks 11 and 18 and support the lamp,forming a yielding carrying means therefor. The socket 17 is adapted toreceive an ordinary incandescent light 2O arranged within the globe 10.Beneath the block- 18 is a butter plate 21, having an opening 22 toreceive the lampvsocket-.-lhe butter pla-te is supported by rods 23 onthe block 11, said rods passing through holes 24 in the block 18 andthrough brackets 25, which are lscoured to the block 11 andA to thecylindrical shell 8, which in turn, supports the globe '10. l am thusable to suspend thp globe and the shell, by which it is carried from thepipe 3, and relieve the lamp socket entirely of the weight of theseparts, which are usually connected with'the socket and render itimpracticable to employ light sup-V porting springs to take vup thevibration and prevent damage to the lamp filament. Seats 26 are formedin the butter plate 21, to reive balls 27 of yielding material, such asrubber. These balls are adapted to Contact with theconeave surfaces28provided in the under siderofthe block 18 and cushion the said block.The distance between the block 18 and the plate 21 can be regulated bythe adjustment of the rods 23.

' It will be not-ed that an important feature f of this inventionisthemanner of supporting the lamp socket and the lamp independently oftheglobe, and at the same time proy viding means whereby the angle of thefixture can be varied to compensate for swaying or rocking of the car,in which the lamp may be mounted. It will also be noted that the domecan he raised to expose the blocks 11 and 18 and allow access to theconnections without the necessity ture 'from the hanger;

I claim as my invention. 1. The combination, th ajcasing and a1 globecarried thereby, block yieldingly" .i

suspended within said casing and having a lamp socket and a lamp fittingtherein, said socketand. lamp being supported independently of saidcasing and globe, the yielding support ot' lsaid block allowing it toswing laterally and move vertically to take up shock orvibrationsubstantiall \7 as decoil springs, and a lamp socket dependingi from said Second block.

4. The combination, with a hanger, of a casing, a block vicldlnglysuspended therein 2l\,anfl having a lamp socket, and means below saidblock for vieldingly resisting its downbaard movement. Y

' The eornlnnation, with a lamp hanger,

Y `of a casing, a block Within said casing havin;r a lamp socket, abuffer arranged below said block and balls of yielding material carriedby said buffer in the path ot' said lilOtl-C.

6. The combination, with a pipe, of a shell supported thereon, a domehaving an Opening to receivesaid shell and adapted to? slide thereon, ablock inclosed by said dome l and having an independentsupport from saidpipe, a lamp socket carried by said block and said dome being,r capableof sliding vertically on said pipe to expose said block and socket.

7.The combination, with a pipe, of a casing` supported thereon, aflampglobe carried b v'said casing, an'd a lamp socketdepending Within saidcasing and yieldingly supported independently of said casing and globe,for the 'purpose specified.

8. The combination, with a hanger, of a..

. block. a yoke mounted onsaid block, a bar supported in said hanger andcarrying said yoke, and a Vplate having a lamp socket yieldinglysuspended beneath said block, substantially as described.

9. A device of the class described, eomprising a casing, a block thereinhaving a lamp socket, a serles of sprlngs yieldi-ngly .supporting saidblock within said casing,

means in the path of said block for yieldingly resisting downwardmovement thereof, and a globe.

l0. The combination, with a hanger, of a yieldingly supported lampsocket pivotally connected therewith,- a casing inclosing said socketand said pivotaluconncction, a shell having a sliding Contact with saidcasing and permitting the'tilting` thereof with respect to said hangerwithout exposing said pivotal connection.'

11. The combination, with. a hanger, of a casing supported thereon, alamp globe carried by said casing, a lamp socket, a spring supportedblock whereonsaid lamp socket is mounted, and a guide permitting alimited lateral oscillation of said block and socket.

l2. The combination of a hanger, a lamp socket pivotally connectedtherewith, a casing inclosing said socket, a shell having a slidingcontact with said casing and permitting the tilting thereof with respect.to said hanger, for the purpose specified.

ln witness whereof, I haye'hereunto set my hand this 17th day of'April1909.
